Urgent! Problem with cooked HTML5 project

Hi!
I got some trouble figuring out why I cannot run my project inside Nightly. Its packing without problem from UE4, zero errors and few warnings mostly materials so that default ones are going to be used. If I package the project for windows it runs without problems.
From the Nightly browser I get one fatal error which is:
Fatal error: [File:D:\Build++UE4+Release-4.13+Compile\Sync\Engine\Source\Runtime\Launch\Private\LaunchEngineLoop.cpp] [Line: 330]
and on the I dont know how to call it “screen”? is this:

LaunchSetGameName(wchar_t*, FString?&)
FEngineLoop::PreInit(wchar_t*)
FEngineLoop::PreInit(int, wchar_t**, wchar_t*)
HTML5_Init()
main()

If I package a blank template scene (FPS) it runs ok in Nightly.
Does the problem have something to do with UE4 at all or its just Nightly problem? Thanks in advance.

Omg I mixed stuff really badly, sorry for the confusion. The error message is from Firefox not Nightly and its:
Uncaught abort("Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value 536870912, (2) compile with -s ALLOW_MEMORY_GROWTH=1 which adjusts the size at runtime but prevents some optimizations, (3) set Module.TOTAL_MEMORY to a higher value before the program runs, or if you want malloc to return NULL (0) instead of this abort, compile with -s ABORTING_MALLOC=0 ") at Error

The Nightly thingy is unrelated.

Nvm, I got it working. :slight_smile:

Hi NasteX,

I’m happy to hear you were able to resolve this error. I will mark this as answered for tracking purposes.

@NasteX how did you got it to work?

@Invius Sorry for late answer, I dont remember. Since this problem I have completely given up on HTML5.
